Revue médicale de Liège

Abstract

Periventricular nodular heterotopia (PVNH) is a cerebral cortex malformation, due to a deletion/duplication in the FLNA gene, located on the chromosome X. The gene is coding a cytoskeleton protein. The transmission is dominant. It enters the heterogeneous group of philaminopathies. There is a feminine predominance. Males most often show early lethality. The clinical presentation is characterised by a seizure disorder ranging from mild to intractable, a mental retardation, hypotonia, cardiovascular abnormalities, vasculopathy and/or coagulopathy leading to stroke. The surveillance must be made by a pluridisciplinary team and the genetic counseling is necessary. We present here a paediatric case.
